Influence of Various Disintegrants on the Quality of Microcrystalline Cellulose Tablets

详细

The effects of the superdisintegrants sodium starch glycolate, croscarmellose sodium, polacrilin potassium Kyron T-314, and Amberlite IRP 88 on the quality parameters of placebo tablets prepared from microcrystalline cellulose were studied. Sodium starch glycolate was most effective with croscarmellose sodium and Amberlite IRP 88 slightly less. All studied disintegrants gave dosage forms of pharmacopoeial quality. The effects of disintegrant concentration and particle type on tablet hardness were determined. The dosage form hardness increased with increasing disintegrant content for croscarmellose sodium with fibrous particles and decreased for sodium starch glycolate and polacrilin potassium with round and irregularly shaped particles. The tablets were harder if polacrilin potassium was added to the formulation.
